SIGNAL SENSE MODES
The CL-SSI is designed to act as a turn-on and
turn-off controller for the CL441dsp, which will
control the turn-on of the rest of the aftermarket
equipment in the system. There are two modes of
turn-on operation which can be selected via the
“SIGNAL SENSE” slide-switch located next to the
CL-SSI’s power connector.
Note:
The “
SIGNAL SENSE
” switch of the
CL441dsp must be set to “
Off
” when used
with a CL-SSI.
Signal Sense: ON
With its “
SIGNAL SENSE
” switch in the “
On
”
position, the CL-SSI will only wake up and turn
on the CL441dsp when it 12V at its “
IGN
”
terminal and also senses an input signal from the
OEM audio source. This mode requires that the
“
IGN
” terminal of the CL-SSI be connected to
a vehicle wire with accessory/ignition-switched
+12V. (See diagram on page 5.)
If the vehicle is turned on with the OEM source
unit turned off, the CL-SSI will remain in Standby
Mode until the OEM source is turned on and
playing. The CL-SSI will go into Standby Mode
(off) approximately one minute after it senses a
loss of input signal or as soon as the ignition is
turned off (whichever comes first).
Signal Sense: OFF
With its “
SIGNAL SENSE
” switch in the “
Off
”
position, the CL-SSI will wake up and provide
+12V at its “
REM.OUT
” terminal whenever it
12V at its “
IGN
” terminal (regardless
of whether the OEM source is on or not). This
position can be useful if another device is being
used to toggle the CL-SSI on/off, or if the OEM
system has a conven12 V turn-on output
(very rare). The “
Off
” position can also be used
with a manual switch on the wire feeding the
“
IGN
” terminal for those who desire manual
control of on/off functions. This switch should
be connected to an ignition-sw12V to
prevent accidental battery drainage.
POWER AND TURN-ON CONNECTIONS
Before installing the CL-SSI, disconnect the
negative (ground) wire from the vehicle’s battery.
This will prevent accidental damage to the system,
the vehicle and your body during installation.
The CL-SSI has a 4-pin inline jack located next
to the “
SIGNAL SENSE
” switch on the signal
output end of the processor (see diagram on page
5). This jack accepts the following connections
through the included color-coded wiring harness
and plug assembly:
“
+12 V
”: Co12V
“
GND
”: Chassis Ground
“
IGN
”: Sw12V
“
REM.OUT
”: Amplifier turn-on (+12V)
Since the CL-SSI does not draw very much
current during operation, 18 AWG - 16 AWG wire
is ample for making all of these connections. Use
good-quality crimp connectors (or solder and
heatshrink tubing) to join the harness leads to any
extended wires. Any wires run through metal
barriers (such as firewalls), must be protected with
a high quality rubber grommet to prevent damage
to the insulation of the wire. Failure to do so may
result in a dangerous short circuit.
Ideally, the “
+12V
” (constant) and “
GND
”
(chassis ground) connections should be run to
the same distribution points that the amplifiers
and CL441dsp use for their power and ground
connections. This minimizes the possibility of
noise in the system.
The “
REM.OUT
” (Remote Output) connection
provides turn-on voltage to the CL441dsp, which
in turn will provide turn-on voltage to the rest of
the aftermarket audio equipment in the system.
The CL-SSI will only turn on when +12V is
present at its “
IGN
” connection. Conversely, the
CL-SSI will immediately shut off as soon as +12V
is removed from this connection. If the OEM
system does not provide a +12V turn-on lead
(most do not), we recommend that you connect
this wire to a 12-volt circuit in the car that is only
energized with the key in the “Accessory” (ACC)
or “Ignition” (IGN) positions. This will ensure
that the audio system will only operate with the
key in ACC or IGN positions. If the OEM system
provides a +12V turn-on lead (rare) you can
connect this turn-on lead to the “
IGN
” connection.

POWER AND TURN-ON CONNECTION DIAGRAM
The CL441dsp’s “SIGNAL SENSE” switch must
be set to “OFF” when used with the CL-SSI. The
CL-SSI will act as the CL441dsp’s signal-sensing
turn-on control. The CL441dsp will provide the
turn-on voltage to the rest of the system, ensuring
that the equipment will turn on and off in the
appropriate order, eliminating pops and thumps.
FUSE REQUIREMENTS
The +12V constant wire on the CL-SSI power
harness has an inline 1 amp, fast blow AGC (small
glass-bodied) fuse for protection of the unit. Do
not remove this fuse or replace it with a different
value of fuse.
